Fog lifts off Byram Lake on cold spring mornings and hangs in the low ground west of the village until the sun finally burns through it. Forever Green Landscape Services Inc. is usually out in that hour already, mowers on the trailer, the first cut of the season waiting. The work runs the whole calendar here — mowing, trimming, edging, mulch and seasonal cleanups, then snow plowing, walkway clearing and salting when Mount Kisco goes white and the reservoirs go still. A drive cleared before breakfast and a lawn that holds its stripes for a week are the same skill wearing different boots. The service area reaches Bedford Hills, Katonah, Armonk and out along the roads toward Somers.
